Due to congenital deformities, trauma, infection and even the difficulty of treatment costs and the lack of medical technology, many patients with spinal deformities do not receive timely treatment at an early stage, and their condition gradually worsens as time passes. These patients can often develop severe kyphosis and scoliosis deformities. Due to the loss of spinal balance, the spinal force lines are significantly displaced, which causes local pain, restricted movement, and even severe neurological dysfunction due to long-term spinal cord compression, seriously affecting the patient’s appearance, heart, lung, and abdominal organ function, resulting in a significant decrease in quality of life. Due to the large posterior convexity, patients often have difficulties in treatment, and the difficulty, risk and cost of surgery are so great that most hospitals in China are not yet able to carry out surgical treatment for these patients. This year we admitted some patients with very severe kyphosis. One of them is a typical patient – Tian×, female, 27 years old, from Shou County, Anhui Province. Her hunchback deformity was discovered when she was a toddler. Since the domestic medical technology at that time was not able to complete the surgical treatment of this spinal deformity, although she sought medical help everywhere, she had not been able to get effective treatment, and as she grew older, the patient’s hunchback deformity developed to an extremely serious stage. Unable to lie down, walking difficulties, no quality of life to speak of. In August this year, he was referred to my specialist clinic. Before admission, a full spine X-ray showed that the thoracolumbar spine was 150 degrees posteriorly convex and 80 degrees laterally convex. After detailed preoperative examination, he was admitted to the hospital and under general anesthesia on 2013-08-13 for a posterior two-segment expanded transforaminal osteotomy (PSO osteotomy) + multi-segment Smith-Peterson osteotomy (SPO osteotomy). After surgery, the X-ray was reviewed: 10 degrees of thoracolumbar lordosis and 20 degrees of lateral lordosis. The patient and her parents could not believe such a huge change.
